each channel has a bi-color led to indicate positive (white) or negative (red) signal
video-rate opamps, for greatest bandwidth of any buffered mult. fully compatible with lzx and video signals
bottom channel is normalized to top channel, for a 1-to-6 multiple
useful for detecting signals, troubleshooting patches, isolating modules, live patching, and protecting modules
